DETAILED DESCRIPTION

In the following paragraphs, some embodiments of the invention will be described by way of example and not limitation. It should be understood based on this disclosure that various other modifications can be made by those in the art based on these illustrated embodiments.

Hereinafter, embodiments of a form changing toy according to the present invention will be described based on embodiments shown in the drawings. In the present specification and the scope of claims, when referring to “actuation device”, it is a power source including a power transmission, an individual operation mechanism operating a predetermined operation part, and a power transmission mechanism which transmits power to the individual operation mechanism from the power transmission. Further, the phrase “movable parts” is defined as a part contributing to form changing in the operation parts. In certain embodiments, a switch is a part of the movable part to perform moving.

First Embodiment

A form changing toy 1 shown in FIGS. 1 and 2 is shaped as a beetle, and includes components of a body part 2, a head part 3, leg parts 4, a horn part 5, etc. In the body part 2, a power spring is provided as a power transmission.

In the state shown in FIG. 1, a lower horn (operation part) of the head part 3 moves up and down by the power transmission, and the form changing toy 1 moves forward by operating the leg parts (operation parts) 4.

Further, as shown in FIG. 2, when the form is changed to manually expose an upper horn (movable part) 5 b to the front side from the upper side part of the head part 3 and the body part 2 by hands, the form changing toy 1 moves forward by the leg parts 4 by the power transmission, and the upper horn 5 b is moved up and down. In other words, the upper horn works as a switch to perform the movement in up and down.

FIG. 3 shows an operation mechanism 6 of the leg parts 4. The leg parts 4 are provided with right and left front legs 4 a, right and left middle legs 4 b, and right and left back legs 4 c. Among these legs, the right and left middle legs 4 b are secured to the body part 2. Further, the right and left front legs 4 a are connected to each other by a connecting rod 6 a, and further, the right and left back legs 4 c are connected to each other by a connecting rod 6 b. A middle part of each of the connecting rods 6 a, 6 b is rotatably supported to the body part 2 by shafts 6 c, 6 d.

Further, in a position off to the shaft 6 c in the front side connecting rod 6 a (e.g., left side position) and in a position off to the shaft 6 d in the back side connecting rod 6 b (e.g., right side position), a connecting rod 6 e is rotatably connected. In a middle of the connecting rod 6 e, a hole (not shown) is formed. On the other hand, in the body part 2, a gear 6 f is rotatably supported, and an eccentric shaft (not shown) is projectingly provided in an eccentric position of the lower surface of the gear 6 f The eccentric shaft is engaged to the hole of the connecting rod 6 e.

Further, in the middle of the body part 2, a power spring (not shown) is provided as a power transmission. An output shaft 7 of the power spring extends in a vertical direction, and a gear 7 a is securely provided in the output shaft 7. The gear 7 a meshes with the aforementioned gear 6 f.

In the leg parts 4, when the gear 7 a rotates by the spring power, the gear 6 f, which meshes with the gear 7 a, rotates, and accordingly, the connecting rod 6 e engaging with the eccentric shaft swings. With this structure, the front and back connecting rods 6 a, 6 b swing in opposite directions with respect to the shafts 6 c and 6 d. One of the right and left front legs 4 a moves forward, and the other one of the right and left front legs 4 a moves rearward. Further, the other one of the right and left back legs 4 c moves forward and one of the right and left front legs moves rearward. Accordingly, the form changing toy 1 moves forward.

FIG. 4 shows an operation mechanism 8 of the lower horn 5 a. The lower horn 5 a is supported by a shaft 8 a of the base end. The shaft 8 a is rotatably supported to the frame of the head part 3, and the lower horn 5 a is always urged downwardly by its own weight. In the shaft 8 a, a bracket 8 b is secured. On the other hand, in the upper end part of the output shaft 7, a disk cam 8 c is securely fixed. In a position between the circumferential surface of the disk cam 8 c and the aforementioned bracket 8 b, an actuation piece 8 d is arranged movably back and forth in the frame. The actuation piece 8 d is always contacted to the circumferential surface of the disk cam 8 c by the bracket 8 b.

According to the operation mechanism 8 of the lower horn 5 a, the disk cam 8 c is rotated by the rotation of the output shaft 7, and when a ridge of the circumferential surface of the disk cam 8 c is directed toward the actuation piece 8 d, the actuation piece 8 d is pressed by the disk cam 8 c and it is moved forward. Then, the top end of the actuation piece 8 d presses the bracket 8 b, and the bracket 8 b is rotated in a clockwise direction, and therefore, the lower horn 5 a rotates upwardly. Further, when a valley of the circumferential surface of the disk cam 8 c is moved toward the actuation piece 8 b, the pressing force to the bracket 8 b releases, so that the lower horn 5 a is rotated in a counterclockwise direction by its own weight in FIG. 4, and the actuation piece 8 b moves rearwardly while contacting with the circumferential surface of the disk cam 8 c.

FIGS. 4 and 5 show an operation mechanism 9 of the upper horn 5 b. FIG. 4 shows a state in which the upper horn 5 b is stored inside an upper cover 2 a constituting an upper part of the body part 2 and the head part 3. FIG. 5 shows a state in which the upper horn 5 b projects to the front side.

The upper cover 2 a is mounted on the body part 2 through the rotating body 2 c. The rotating body 2 c is rotatably mounted to the body part 2 by the shaft 2 b. A slide body 9 a integrated with the upper cover 2 a is supported by the rotating body 2 c in a movable manner in a front and back direction. The slide body 9 a is formed in a u-shape in which the cross-section surface (cross-sectional surface perpendicular to the slide direction) releases downwardly. In the back end of the slide body 9 a, a cam follower 9 b which extends downwardly is formed. The disk cam 8 c and the cam follower 9 b are parts of an operation mechanism.

The base end of upper horn 5 b is rotatably supported to the slide body 9 a by the shaft 9 c. The upper horn 5 b is folded and stored in the slide body 9 a as shown in FIG. 4. On the other hand, an end-face cam 9 a is formed on the upper end surface of the output shaft 7. As described later, the end-face cam 9 d is formed in a manner of being capable of contacting with the cam follower 9 b of the slide body 9 a.

As shown in FIG. 4, before changing form, the upper horn 5 b is stored in the slide body 9 a. This is a state in which the slide body 9 a is pressed in a rear side, so that the cam follower 9 b is located in a position separated from the end-face cam 9 d.

When the upper cover 2 a is opened upwardly, the upper horn 5 b is rotated in a clockwise direction around the shaft 9 c as a center. When the upper horn 5 b is pulled out, the slide body 9 a moves forward to the upper cover 2 a. With this, as shown in FIG. 5, the cam follower 9 b contacts with the end-face cam 9 d. In this state, the integrated upper cover 2 a, upper horn 5 b, and slide body 9 a (hereinafter referred to “upper horn assembly”) maintain an opened state by the cam follower 9 b.

The upper horn assembly moves up and down in accordance with the rotation of the end-face cam 9 d. That is, when the cam follower 9 b contacts with the ridge of the end-face cam 9 d, as shown in FIG. 5, the upper horn assembly is positioned at the uppermost position. When the end-face cam 9 d reaches the valley, the upper horn assembly is rotated in a counterclockwise direction around the shaft 2 b as a center by its own weight so as to move downwardly.

Second Embodiment

A form changing toy 10 shown in FIGS. 6 and 7 is shaped as a turtle, and includes components of a body part 11, a head part 12, and leg parts 13, etc., and a cannon 14 is stored inside the body part 11. Further, the form changing toy 10 is provided with a motor as a power source including a power transmission for the body part 11.

In a state shown in FIG. 6, in the form changing toy 10, by the power transmission, the leg parts (operation parts) 13 are operated so as to move forward, and the head part (operation part) 12 swings up and down.

Further, in the form changing toy 10, as shown in FIG. 7, the upper cover 11 a which forms the upper side part of the body part 11, opens upwardly, and the top end of the cannon (movable part) 14 is exposed. When the form is changed by pulling the cannon 14 out in a forwardly obliquely upward direction, the leg parts 13 are operated by the power transmission so as to move forward, and the cannon 14 is connected to the power transmission, and therefore, the cannon 14 appears in the front and back direction.

FIG. 8 shows an operation mechanism 15 of the leg parts 13. The leg parts 13 are provided with right and left front legs 13 a and right and left back legs 13 b.

A shaft hole 150 a is formed on the back side of a middle part 15 a of the right and left front legs 13 a, and in the shaft hole, an eccentric shaft 151 a of a rotation body (not shown) provided in the body part 13 is fitted in the shaft hole. Further, an elongated hole 150 b is formed in the back surface of the upper end part 15 b of the right and left front legs 13 a, and the shaft 151 b fixed in the body part 11 is inserted into the elongated hole 150 a. Further, in the shaft 15 c of the lower end part of the right and left front legs 13 a, a grounding member 13 c is rotatably supported (see FIG. 10).

On the other hand, a shaft hole 150 d is formed in the back side of a middle part 15 d of the right and left back legs 13 b, and a shaft 151 d fixed in the body part 11 is fitted into the shaft hole (see FIG. 10). Further, in the shaft 15 d of the lower end part of the right and left back legs 13 b, a grounding member 13 d is rotatably supported.

Further, the lower part of the right and left front legs 13 a and the upper part of the right and left back legs 13 b are connected to each other by a connecting rod 15 f.

According to the operation mechanism 15 of the leg parts 13, in the right and left front legs 13 a, the front legs 13 a swing through the eccentric shafts 151 a by rotating the rotation body of the back side of the middle part 15 a. Such movement of the front legs 13 a transmits movement to the upper part of the back legs 13 b through the connecting rod 15 f, so that the back legs 13 b swing around the shaft 15 d as a center. Therefore, when the front legs 13 a swing in the forward direction, the back legs 13 b swing in the rearward direction.

By the way, in the operation mechanism 15 of the leg parts, the aforementioned eccentric shafts of the right and left front legs 13 a are positioned with 180 degrees phase difference each other. That is, when the left front leg 13 a swings in the forward direction, the right front leg 13 a swings in the rearward direction. By repeating the movement, the turtle moves forward.

Further, the turtle 10 is provided with an operation mechanism 16 of the head part as shown in FIG. 8. In the operation mechanism 16, a protruding piece 16 a is provided in the front part of the front leg 13 a. On the other hand, the head part 12 is supported to the body part 11 by a shaft 16 b so as to freely swing, and the tongue piece 16 c is provided in the rear part of the head part 12. The tongue piece 16 c of the head part 12 is positioned facing to the protruding piece 16 a of the front legs 13 a. When the front leg 13 a swings forward, the protruding piece 16 a further moves forward, and the protruding piece 16 a presses a tongue piece 16 c. Therefore, the head part 12 rotates upwardly (clockwise direction) around the shaft 16 b as a center. The head part 12 moved upwardly rotates downwardly (counterclockwise direction) by its own weight while the front leg 13 a moves rearwardly.

Further, the turtle 10 is provided with an operation mechanism 17 of the cannon. The cannon 14 is positioned in the upper part of the body part 11, and it is stored in a frame body 17 a which is elongated in the front and back direction. The base end of the frame body 17 is rotatably supported by a shaft 17 b, and the cannon 14 is slidably held in the frame body 17 a. A lever 17 c is rotatably supported in the bottom part of the frame body 17 a. In the top end of the lever 17 c, a cam follower 17 d is arranged, and in the bottom end, an engagement roller 17 e is arranged. The cam follower 17 d is engaged with a groove 14 a formed in a vertical direction in the rear end of the cannon 14.

On the other hand, in the body part 11 facing to the bottom wall of the frame body 17 a, a slide body 17 f which slides in the front and back direction is arranged. The slide body 17 f is provided in the groove 17 g which opens upwardly. The groove 17 g is provided in a fitting manner with a projection 17 e which will be described later.

Further, in the slide body 17 f, as shown in FIG. 11, an opening 170 e is formed, and in the opening 170 e, an eccentric shaft 10 d of a rotary roller 10 c which is fixedly provided in a shaft 10 b associated with the actuation device is inserted.

According to the operation mechanism 17 of the cannon, in FIG. 8, the frame body (upper cover) 17 a opens upwardly (clockwise direction), and the cannon 14 is pulled out by hands. Then, as shown in FIG. 9, the engagement roller 17 e of the lever 17 c is fitted to the groove 17 g of the slide body 17 f. Therefore, after that, the lever 17 c swings in accordance with the movement of the slide body 17 f, and the cannon 14 appears through the cam follower 17 d. This movement continues all the time while the turtle 10 moves forward.

Therefore, the blade-shaped wings 24 swing front and back in a travel direction in accordance with the movement of the slide body 29 a.

Fourth Embodiment

According to another form of the present invention, as shown in FIG. 17, a form changing toy 50 is shaped as a crocodile, and includes components of a body part 51, a head part 52, and leg parts 53, etc. In the form changing toy 50, a motor as a power source including a power transmission is provided in the body part 51.

In the state shown in FIG. 17, the leg parts (operation parts) 53 are operated by the power transmission in the form changing toy 50.

Further, in this crocodile 50, an upper jaw 52 a of the head part 52 and an upper part (back part) 51 a of the body part 51 are integrated as shown in FIG. 19. In these assemblies 54, a rear end part is rotatably supported to the body part 51 by the shaft 55. By pulling the head part 52 forward, an upper jaw (movable part) 52 a is largely opened and closed by linking with the operation mechanism of the leg parts 53.

The operation mechanism 55 of the leg parts has almost same structure as the leg part operation mechanism 15 shown in FIG. 7, and therefore, for the same parts, the same reference numerals are used and the explanation of these parts are omitted.

In the operation mechanism 55 of the leg parts, as shown in FIG. 18, the lower part of the right and left front legs 13 a and the upper part of the right and left back legs 13 b are connected to each other by a connecting plate 56.

By the operation mechanism 55 of the leg parts, the front legs 13 a swing by an eccentric shaft 15 a rotated by the power. Such movement of the front legs 13 a transmits to the upper part of the back legs 13 b through the connecting plate 56 and the back legs 13 b swing around the shaft 15 d as a center. Therefore, when the front legs 13 a swing in the front direction, the back legs 13 b swing in the rearward direction, and the crocodile 50 moves forward by repeating these movements.

Further, the crocodile 50 is provided with an operation mechanism 57 of the upper jaw. In the operation mechanism 57, as shown in FIG. 19, the slide body 58 which slides in the front and back direction is provided. The shaft 55 is arranged in the slide body 58. As shown in FIG. 19, the base end of the upper part assembly 54, which is provided with the upper jaw 52 a of the head part 52 and the back part 51 a of the body part 51, is rotatably secured to the shaft 55.

In the upper part assembly 54, in a normal state as shown in FIG. 17, the slide body 58 (FIG. 19) is positioned in the rear side of the body part and is mounted on the body part 51.

The slide body 58 moves forward by pulling the head part 52 forward. Then, the base end of the upper part assembly 54 is engaged with the connecting plate 56.

In such way, when the base end of the upper part assembly 54 is engaged with the connecting plate 56, after that, it is operated by the movement of the connecting plate 56, so that the upper part assembly 54 is rotated upwardly (clockwise direction) around the shaft 55.

The rotation amount which rotates in the upward direction of the upper part assembly 54 is determined by the pressing amount of the connecting plate 56. Therefore, with such consideration, an appropriate position of the engagement position between the upper part assembly 54 and the connecting plate 56 is set.
